The City of Cape Town has issued a public warning after puffer fish were spotted washing ashore along parts of the coastline following several days of strong southeasterly winds and large swells.
Officials said the phenomenon was linked to recent storm-related rough sea conditions and was considered a normal occurrence during periods of heavy swell activity.
According to the City, puffer fish carry a powerful toxin known as tetrodotoxin, which can be deadly if ingested by humans or animals.
“Even small amounts can pose serious health risks to humans and animals,” the City warned.
Although the fish may appear harmless once stranded on beaches, authorities stressed that they remain highly dangerous and should not be touched or handled under any circumstances.
The City said changing ocean conditions can wash marine life, including puffer fish, onto beaches across Cape Town at any time.
Dog owners urged to remain vigilant
Residents walking dogs along the coast are being specifically urged to keep pets on a leash and away from any marine animals washed up on shore.
“We advise the public please to keep their dogs on a leash and not allow their pets to come into contact with the fish, or consume the fish or any other marine animals,” the City said.
Officials warned that dogs are especially vulnerable because they may attempt to sniff, bite or eat the fish.
“Ingesting even a small amount can be fatal,” the City added.

Beachgoers react to warning
Several beachgoers said they were surprised to learn about the dangers posed by puffer fish washed up along the shoreline.
Table View resident Melanie Jagers said she often walked her dogs on the beach and would now be extra cautious.
“I had no idea they were poisonous. My dogs sniff everything on the beach, so this warning is definitely important.”
Bloubergstrand surfer Darren Crane said he had noticed unusual marine life washing ashore after the recent strong winds.
“The sea has been really rough lately, and you do see strange things washing up after storms. People need to be careful and not touch anything.”
Beach walker Connie Murphy said the warning was a reminder for parents and pet owners to stay alert.
“A lot of children and dogs get curious when they see fish on the beach. It’s good that the City is warning people before something serious happens.”
Public asked to report sightings
The City has encouraged beachgoers to remain cautious while visiting coastal areas, noting that puffer fish could wash ashore “at any time, at any given location” while rough sea conditions continue.
The public was also advised to avoid touching any marine animals found on beaches.
Authorities said public reporting helps officials monitor the situation and alert others to potential dangers along the coastline.
